First, the mega-mat foundation construction technologies are shown, including ultra-low heat concrete, heat of hydration control programs, and the logistics plan. Then, high strength concrete technologies of 50~80 MPa are introduced and discussed within the context of the highest pumping record in Korea at 514.25 meters. Structural design concepts of gravity load and lateral force resistance systems are introduced, along with surveying systems using GNSS and temporary installation plans of special heavy equipment like tower cranes, hoists, and high pressure concrete pumps. -

Vertical Transportation: Ascent & Acceleration
Tall Buildings in Numbers Vertical Transportation: Ascent & Acceleration As part of a recent collaboration with the Guinness Book of World Records, CTBUH certified that Shanghai Tower has the fastest elevator and the longest elevator run of all commercial buildings in the world. Expanding upon this study, CTBUH sought to determine the records for speed and length of run among the world’s tall buildings. The findings and related data are displayed here.
